So the proposed solution was to shorten my stride in an attempt to reduce the bounce and the impact on my body with each stride. It has been about a month since I had the analysis done, and I have had middling success with making changes. I went from about a 162-164 average cadence to about 168-170 or so, and from a stride length of about 1.4m to about 1.3m. It took two weeks for it to not feel weird while running, and my body is still adjusting some. I also tend to default to a lower cadence as I tire.
Lots of background in there, but I thought it might be interesting to hear since you are considering some changes. The bottom line is that I suspect that 6' 1" runners tend towards a 180 cadence on easy runs as much as runners of other heights. But if you don't have any significant injury issues and are not over-striding, I wouldn't worry about it too much.
What pace is that at? And is it on a flat, hard surface? Yea mine was probably way below 160 before I started working on it so maybe where it's at is good. When I get down to 7:30 pace it tends to be above 170 and anything faster than about 7:00 mile pace is pretty close to 180 or higher.
I find it interesting to think that height doesn't make a difference....aren't longer legs, longer pendulums which take longer to swing? I'm also aware that loads of the fast distance runners and short guys with a quick snappy turnover.
